After filling teeth, tooth allergies are quite common. Dental fillings may be sensitive to stress, sweets, temperature and other stimuli. This sensitivity usually disappears by itself within a few weeks. When you are sensitive, it is enough to avoid irritation as much as possible, and generally no painkillers are needed.
If the tooth allergy does not relieve within two to four weeks, or your teeth are very sensitive, you can contact the dentist. He/she may suggest that you use desensitizing toothpaste, tooth desensitizer, or root canal therapy.
Generally, there are the following kinds of discomfort after filling teeth.
1, pain caused by filling
You will feel pain when you bite or the cusp is opposite. This kind of pain appears soon after the anesthesia subsides, occurs when chewing food and lasts for a period of time. This kind of pain shows that filling interferes with the occlusal relationship of teeth and requires follow-up visit and filling and plastic surgery. If the pain persists, it may indicate the need for root canal treatment.
Cold and heat stimulate pain. This kind of pain is very intense, and it will only appear when the teeth come into contact with cold or hot things. After the cold and hot stimuli are removed, the pain will disappear. If the pain lasts for a long time after the cold and hot stimulation is removed, it means that the nerve may be irreversibly damaged. In this case, you should consult a dentist.
Constant jumping pain. If there is a deeply decaying root, this pain indicates that the pulp tissue may no longer be healthy and may require root canal treatment.
It involves pain (sensitivity or pain of adjacent teeth when filling teeth). There seems to be nothing wrong with the teeth except the unique pain. This is because the filled teeth will send a pain signal to other teeth, and the pain should relieve itself within one to two weeks.
2. Allergic reaction caused by amalgam filling.
Allergic reactions caused by silver fillings are very rare. According to the American Dental Association, the number of reported cases is less than 100. This allergic reaction may be caused by mercury and other metals. The allergic symptoms of amalgam are similar to typical skin allergic symptoms, including rash and itching. Patients who are allergic to mercury usually have a history of metal allergy or a family history. If the allergy is confirmed, it can be filled with another repair material.
3. Problems caused by inferior filling materials
The pressure caused by continuous chewing, grinding teeth and clenching teeth may consume the fillings of teeth. Although you don't know that the fillings of teeth have worn out, dentists can diagnose the defects of restorations during regular health checks.
If the adhesive between enamel and filler is cracked, food residues and caries-causing factors will enter the gap, causing secondary caries.
If the filling range is large or there is secondary caries, the remaining tooth tissue may not be enough to support the secondary filling. In these cases, dentists may need to replace fillings with crown restorations.
The new filler falls off, which may be caused by the fracture of the repair material under the action of chewing or occlusion. However, longer prosthetic materials are usually worn out due to dental caries or the fracture of remaining teeth.
Therefore, dental restoration is not once and for all, and it needs regular inspection after restoration, early detection of problems and timely treatment.
